Loss of power/bogging out

Good day. 2018 pro has been losing power lately. I usually warm up a few minutes before driving and upon shifting into D or R the truck bogs down sometimes but not enough to stall out. After I give it gas it may bog down again then it is good for the rest of the way.

I have had the fuel pump replaced by the recall. Any ideas what causes this or similar experiences?

 

How long after new pump install ? Maybe related to the fuel pump ?

 

I had the pump changed in December, no issues prior to the pump recall. I have put about 4k miles on since then.

 

Are you out of warranty already?

 

No I have extended warranty for about 15000 more miles

 

Do you have a scan tool ? If so I would suggest seeing if there are any codes in system,possible in pending.
Next step get fuel pressure gauge and see what fuel pump pressure is when this happens. possible defective fuel pump or pump screen partially plugged with dirt. However if it were a fuel starvation problem i would think it would happen more times then not..LAST, possible bad mass air flow sensor ???

 

Might try running a bottle or two of some Chevron Techron through the fuel system. Maybe the intake system / injectors just needs a little cleaning.

 

Maybe use the warranty you paid for?

 

Thanks I will give that a shot

 

The OBD just came back all good. I have a service appt in a couple weeks and will mention your suggestions..thanks

 

Well that's the plan "unless they pull the unable to duplicate complaint bs" then I will use any information gathered here to try and fix the problem myself with some very mechanical buddies I have.

 

Hey thanks for letting me know, please keep us updated.

 

Any updates on this?
